Definitions

  • This invention relates to a water loss detector and particularly relates to a device for use in connection with water closets.
  • a supply of from forty to fifty gallons of water per day per inhabitant is generally provided in any city or town. So for a city of one million people, the supply of water to be made available should be about 50,000,000 gallons per 24 hours.
  • the toilets are mentioned just because they are certainly the source of the greatest proportion of the waste of water. I am considering the common type of water closets. This study is not concerned with the flushamatic type, although it also could present some defects. In fact, a low percentage of the water closets are of the flushamatic type, which requires a supply having a high pressure.
  • Waste of water coming from this source may be unlimited.
  • the hollow 'ball follows the level of the water and carries the rod which from its horizontal position descends towards the bottom of the tank, making then with the horizontal an angle of more than 30 degrees, when the tank is completely emptied. In this position, the rod does not convey any pressure to the valve of the filling pipe. The said valve is then opened and the water flows into the tank. If the working is normal, as soon as the tank is emptied, the valve controlling the opening and the closing of the discharge pipe descends and closes the discharge pipe, so that the water coming from the filling pipe now refills the tank. The water level rises gradually. The hollow ball follows this movement and the rod reascends in order to reach its horizontal position, which determines the closing of the filling pipe valve.
  • I utilize a circuit, being able to unlatch an alarm and having a time basis, which closes or opens according to the angular position of the hollow ball rod with respect to the horizontal.
  • One object of this invention is to provide a system for V detecting water waste.
  • a further object of this invention is to provide a system for detecting malfunctioning in. a water closet.
  • A'third object is to provide a simple and reliable apparatus which may be used to determine continuous water fiow and wastage in a water closet.
  • Still another object of this invention is to provide a simple and readily adjustable device which will provide an indication when the water in a water closet hasnot reached desired levels.
  • FIG. 1 is a sectional view of a conventional Water closet illustrating my invention.
  • FIG. 2 is an enlarged top view showing my invention mounted on the ball rod.
  • FIG. 3 is a side view showing the position of my invention on the ball rod.
  • FIG. 4 is an enlarged sectional view along the lines 44 of FIG. 3.
  • FIG. 5 is a schematic diagram illustrating my control system.
  • FIG. 5A is a detailed circuit diagram.
  • FIG. 1 there is shown a conventional water closet 10 having a tank 11 and a flushing handle 12.
  • valve V controlled by a rod 32, the other end of which has a hollow ball secured thereto.
  • valve V When the ball'is in the position shown in FIG. '1, valve V is closed, but when the ball is lower because of the water level being at a lower than desired level, valve V is'open.
  • a clip portion 45 is part of the plate 44, which clip holds a mercury liquid switch.
  • the bottommost plate 40 can be generally flat and the securing plate 42 can be flat and having a clamping section such that the rod 32 can be held between these plates when they are screwed together.
  • a plate 44 has an arcuate slot 47 and a pivotal point 48 which may, for example, be a screw. The position of the screw for slot 47 determines the angle of the clip holder 45 with respect to the horizontal and necessarily the mercury switch 46 which is secured thereto.
  • the position of plate 44 may be adjusted so that the mercury switch 46 is at a horizontal position.
  • the mercury switch 46 is at a horizontal position.
  • the rod 32 is at a greater than desired angle, the mercury switch itself will be placed at an angle and will effectively be closed.
  • FIG. 5 illustrates a simple alarm diagram and while this invention will be explained in conjunction with a buzzer 60, it will be understood that other indicating devices may .relay 56.
  • the time delay relay or other time delay control means is intended to provide operation of the alarm after the normal cycle of a working water closet. Relay 56 will close an associated contact 57 when it is actuated.
  • Contact 57 is in series circuit with the alarm 60 and the AC. source 50.
  • A.C. signals will be recti-- fied at 52, and will gradually build up a charge on the capacitor of the time delay relay 56. When this charge reaches a predetermined level, contact 57 closes and the alarm 60 is actuated.
  • FIG. 5A shows essentially the same circuit except that a full wave bridge rectifier 52 applies its output over a variable potentiometer 54.
  • the capacitor 55 of the time delay relay is also shown. The actual time delay may be varied by the setting of the potentiometer 54.
  • the rod passes gradually from its horizontal position to its position of rest, which indicates an angle of about 30 degrees with respect to the horizontal, within 8 seconds.
  • the valve at the bottom of the tank closes the discharge pipe and the tank is being refilled, the angular position of the hollow ball rod with respect to the horizontal is about 20 degrees, within 10 seconds.
  • the alarm resounded, and stopped only when the tank is half full, that would rather constitute a nuisance for the user.
  • the device must only warn the user when the Working of the water closet is improper. The switch closes itself,"
  • the angular position of the hollow ball rod will exceed 25 degrees and will open itself, when this angular position with respect to the horizontal will be less than 25 degrees.
  • the rod occupies an angular position with respect to the horizontal, varying from 25 to 30 degrees and from 30 to 25 degrees, it will be allowed enough time, for example, 20 seconds, beforethe alarm is unlatched. So the switch closes itself, as soon as the position of the hollow ball rod with respect to the horizontal is 25 degrees. The rod continues to descend to attain its maximum angular position with respect to the horizontal. Then, if the working of the water closet is normal, the valve at the bottom closes the discharge pipe. The tank is being refilled.
  • the hollow ball ascends and the rod leads gradually from its position of rest to its horizontal position. Within 10 seconds, its angular position with respect to the horizontal is about 24 degrees. At this moment, the switch opens itself. If, then, the arrangement of the switch is as specified and the circuit set to unlatch the alarm, let us say after seconds, the alarm will not resound, if the working of the water closet is normal, that is to say, if there is no important loss of water or if there is no defect in the water supply system.
  • the mercury switch with tilt action makes contact when its angular position towards the bottom with respect to the horizontal is three degrees.
  • the circuit would be closed as soon as the angular position of the rod with respect to the horizontal would be three degrees, because the mercury switch makes contact when its angular position with respect to the horizontal is three degrees.
  • the circuit is closed at least when the angular position of the rod with respect to the horizontal is about 25 degrees, and due to the imperfections of some models of water closet, I am able to vary the angle of closing or opening of the switch, according to the genuine angular position of the rod at rest with respect to the horizontal.
  • said switch means including a bracket having means for supporting a mercury switch, said bracket having means for variably fixing the indicator position of said mercury switch.
  • bracket comprises a bottom plate and a rod-securing plate and further including a switch supporting clip means.
  • timing means includes a line delay relay controlling said switch means.
